Sounds very good. We should also ask ourselves however, does the difference in power given almost twice the size in displacement, justify the extra pound or so? Believe me guys, i'm a FIRM believer in "IF IT AIN'T BROKE, DON'T FIX IT" LOL!! I for one, just truly love what i've seen in the OS 91/Dynamax combo. I can also truthfully say, i've never seen a Turbax powered model. I'm not for knocking what I haven't tried. I guess it comes down to what it always does....personal preference. Bob, at this point I think it's safe to say, with this particular model, whatever you choose will do just fine. Knock em dead!!!
