For me, full bucket for long distance is not that bad, i've been using Full Bucket all the times, if possible, dont get Japanese full bucket, they are really thin and torture your a$$ but they are light enough

Personally i'm using european bucket, slightly heavier than japanese one but no problem for long distance

Mine is Kingdragon
Original from Italy with FIA certified

Yup, SPG is nice, i tried it once before and really like it, but the Low Max is not nice, the backbone area is for me.

Yup, the SPG is replica, comes with universal railing, seriously, no idea how to know find out whether it's genuine or not, as look from the pic, it has labels as well

Owned more than 15 pairs of car seat.

Actually, for full bucket seat, IF YOU GET one with the right size, with the right height, and right angle, it is much better than a semi bucket seat. That's mean, you have to get a correct seat rail and adjust the seat height and leaning angle. Trust me, you can ask ktek regarding my statement. We both traveled with full bucket in long distance non stop for almost 300km without pain in the a$$ or waist ache.

While SSCUS? Good looking but bad sitting quality, no grip, no wrap to ur body, and one thing for SSCUS, you have to get a brand new one, those used one usually is not that good as the sponge quality is bad and wont last long.

While replica? Oh my.... Well it has exact shape but the sponge is so thin and u just like sitting on the shell of the seat, and the shell is made by using single layer of FRP, my friend broke the wing of a Bride Low Max, the shoulder part terus patah
But they do made good quality one, if you guys still can find, go for the carbon or Kevlar Low Max replica, those are better, just better.

Semi bucket is harder to maintain if you always fetch noob passenger, the thigh and waist support of the seat will be a goner if you don't know how to take care of them.

Seat that I owned before
Recaro Profi SPG
Recaro SR3 Type R, Evo 3, Evo 4 batik, Evo 5
Recaro Tomcat (my office chair)
Recaro SR4
Recaro N-Joy
Bride Zeta II
Bride Artis I
Bride Brix I
Sparco Rev (blue)
SSCUS Viper 611 Silver
SSCUS Viper 110 Red (modded to my gaming seat)
SSCUS Edition

With the original railing from SSCUS, you womt feel the support of the thigh area. As the seat rail is quite low for ur thigh to feel that. It is hard if the sponge of the seat is still in good condition but if it is a daily, it gets soften quite fast, maybe in 2 years.

I didn't buy new, all from halfcut or used, some with ori fabric some rewrapped. Hehe....depend on condition but I prefer all original. Their sponge last for almost forever.

Yes, they do hold well, because all of them are replica of actual product
Exactly the same!!!

SSCUS Corsa - Recaro SPG
SSCUS Eco - Bride Gardis
SSCUS GTR - Charge Speed Spiritz SS

While your SSCUS NSI is actually Sparco Star, we can feel it is good because it is a replica in shape but the sponge is no where near the original manufacturer, but of course la, we get what we paid for

Anyway, you have a very nice seat, SPG-N is a light weight version, smaller and lower.
Recaro has slightly heavier weight compare to Bride and Sparco full bucket seat, because the sponge is much thicker Anyway, all Recaro full bucket seats are very comfortable!!!

Hmmm....yes, for new they are very great, firm and comfy, but if daily for few years, sure it is a goner liao.
Maybe last time my seats were all under extreme sunlight exposure

But SSCUS got memory foam? I see my seat all no my butt shape
