I paddle the Suwannee R. which is full of limestone (sharp) so I need some good thickness on the bottom. I dont know what a T rescue is so the deck doesnt need much cloth at all. 100 yds is nice to have. I get 4oz for $4-$5 a yd from US Composites. Ive been checking out Ebay lately and there seam to be some good deals. dont know about quality but I'll check it out anyway. I feel that using less glass is better. Just be prepared to carry some minicel foam to patch any holes I guess.
