I can see your dilemma. I have an MXT I bought used and it came with both the 4X6 sniper and the 5.3 as well as the stock coil. My first outing was to a very trashy park where it turned out the stock coil was nearly useless. I switched to the sniper and the difference was like night and day. The sniper slipped thru the trash and separated the good targets very well. I definitely fell in love with that little devil. However, I also own 3 Tesoros and a Prizm !V that i picked up this winter. It IS nice to have some sort of a back up. Guess this really isn't much help, but the small coil is wonderful in trashy areas, if that helps you to decide.
