I'm of the same mindset to are from te pictures I've seen littleBen. For me, I don't see much difference in speed. But the molle design seems much easier to get low to no handshock from if the levers are properly narrowed. I mostly make them as change up to flat bows. I will say though, I think that the more dense heavy woods lend themselves to the molle design since it make te tips very light and it doesn't take much wood to keep te tips stiff. Light, low density woods like ERC and black cherry aren't near as good. Since the wood is so light anyway, mixed wth being unforgiving in how they are treated with low tension strength and Black cherries desire to fret. So with those species you are better with more workjng length. I made a ainew backed ERC molle last year. The levers had to be huge to hold up to just a 40# draw. That one took some work to get the levers stiff after the ainew backing. But it did shoot well. That's my take on this design anyway.
