Better still. Rather than have all of us alledged BME "shills" try to explain what makes his engines different or better, call the man direct and have him explain it to you. I believe you'll find that not much of the 115 is "off the shelf". I'm not going to be the one to publically delve into proprietary engineering belonging to any given company.

Since I'm not a salesman I won't try to sell it to you. You can elect or decline to do that on your own. You always have the "Torch" and "Chroma" lines local to you for a back up. Those and others share a lot of common parts.

Getting back to the original question, the 3w-106 is an excellent engine, just heavy.
