Thanks gents for the advice. I asked OEX about Native and he said it might be better but does not have a rental nor can I find anyplaces to try it. The PA 12 is just too big a yak for my taste and I don't need to stand all the time, just a little bit here and there so maybe a DIY pontoon. Finally my back pain is not chronic and actually can continue to do heavy weight training 5 days a week but just go heavy on any exercise that puts compression on spine. I've had this injury for over 20 years. I can even mountain bike with no problems at all and that's why I thought the peddle system would work. Looking into best seats to upgrade to now as well as DIY upgradess on ytube.
