<div> In the last 3 years I've gone from YS DZ140 to OS 160 back to a YS DZ160 and now AXI Electric. I've pretty much decided to stay E at this point as things are going pretty well at this point. As far as what I think about YS. I think if your going IC then for my money YS is the best. They are far from perfect but when they work they are impressive. I've come to think of them as high performance engines on a race car. They are pushing the limits and they are going to have expected failures. Just as a high performance Electric setup does. Its just part of the deal. YS engines are awesome performers. When I had the OS I always felt that I was leaving something on the table from a performance standpoint. But hey its just my opinion.</div> <div> Mike<BR><BR><B><I>colin chariandy <cchariandy@yahoo.ca></I></B> wrote:</div> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid"> <DIV>I'm losing sleep
