I've been fooling aorund wtih a Jimmy Tarps alpine basin I purchased used here and am sadly having a hard time with the pitch. I" lay it out like a supertarp, stake the back 2 corners, then the front pole is inserted and guyed out, then left and righ t front stakes thenback pole and rest of staking. Issue I'm having is a ton of "sweep" in the front seams. and the back seems almost baggy, but the pole definitely can get longer there. The specs I"ve found say 48" front, 31" back. But it almost seems like the front needs to be taller. Any suggestions from anyone who has had one? Here's a pic of what I'm talking about. Thanks!
