Yeah, I got the end caps with the battens. According to the murrays cat they aren't "racing battens." My old Smyth main had the same battens yours did and I actually thought about switching them out but decided against it (it seems like they don't necessarily require the tips). Anyway, write to Dave about it and he should help. I have heard good things about calvert- mainly from this site and I think he came through pretty good with my sail (but I am irked he didn't put the logo on it - sort of like buying a nice BMW or Merc and having them leave off the symbol - but maybe I am overstating it a little
Here is a pic...not a very good one, but ok I am taking it out tomorrow and will take a pic of the batten ends.
BTW- white pentex
