Well here is where I am at, I had my 720 just rebuilt at SES. I sent it on March 22nd, recieved it back on like May 15th. And that wasnt even during "the on season". I have put about 5-6 hours on the ski, compression tested at 140 when I got it, compression is still at 140. I'm kind of concerned about that, and if it doesnt raise by the end of the year back to the 150 that a new engine should be then I am going to send it back. I know I am picky but if he wants the engine in by the end of the month, then SBT is his only option. He would be lucky to get his engine back by August with SES. I am just stating my personal experience, plus I had about a week or two worth of setbacks due to "shipping issues". It almost feels like those shipping issues are just an excuse to give him a little bit more leeway and time, but I am glad to have my engine in and running good right now. I would use again, but I would send my engine in in like December and not so close to the season.
