In my opinion the quality of the EP sails are not very good. We had the head pull out of a brand new I20 main during the Steeple Chase causing us to retire on the first day. The trip to the regatta cost so much and was wasted with using such poor quality EP sails. We have never had a sail fail on any of the Infusions that we have owned with the performance sails. EP does not sew in any straps like the Performance sails you have to do that on your own and now it sounds like you have to have your kite stitched. It seems like you have to do a lot of work to brand new sails if you buy from EP. EP has known about the grommets pulling out for years but yet they still don't sew straps in there sails.
