Surf to summit GTS

Anyone try s2s GTS type seat on a Hobie prior to Vantage?
Your experiences would be welcomed.

I have one on my revo. It helps with the back problem, but I still put extra air cushion for my ass (I'm a skinny dude, so lots of bony prominence). It took me a couple of trips to get used to the extra pads raising cog. Overall, much better than the stock hobie seats.

I tried and it didn't work for me.  It doesn't have the lumbar support like the stock Hobie seat. My lower back was rubbing hard while pedaling.  It was causing me a lot of discomfort.

.... and an uncomfortable Mel is an unhappy Mel 

I  just feel like leaning back too far even with uprighting all the way. Maybe a stiff splastic board or a supporting box behind the back to limit the rearward leaning may help. A good winter project.
