I love the ES gear. I have the shorter set on my Partner and I've flown the taller set some on a good friend of mine's e-Impact. I would think that it would be easier to Dremel out the little semicircle for the gusset in the fuse on the underside of the leg than it would be to widen the slot, not to mention the fact that the surgery will be invisible. FWIW, I hit a pot hole on the runway at site four at the Nats during practice and it jarred the airplane hard enough that it would have either broken the gear leg or mount, but I didn't have any damage whatsoever to my airplane. That's in and of itself just made the price of the gear worth it to me. Good luck with your choice!
