Just an interested subscriber here, but the 7 offers the "lo hole" 1st gear and ends up the same in 7th as the stocker does in 6th right? I just read the website and they talk about basically keeping the motor in the best of the powerband, the sweet spot if you will. As broad as the powerbands are on these things that sounds like fun but only if you want to shift it because you like to shift it. Having to grab another gear surely isn't going to make it faster going in a straight line! ( Point of reference here, Coming from a 5 speed I'll go to a 6 speed when and if my 5 speed ever breaks 
.) Good Luck in whatever you decide to do!

I got a killer deal on a SE 6 speed gear set, Paid my indy to install (no Garage or special tools) Shifts great and the overdrive is nice to have to have but with the extra power I have with the 103" I could have just changed the pulleys and got the same top drive gear ratio. I have never gotten a good explanation on which is better the DD or OD, the final drive ratio is the same for the most part, the DD changes the output gear and the OD is a true OD but the RPMs at MPH are the same if I'm not mistaken, so which has the better mechanical advantage?
Getting around to answering your question, a DD trans would be best, as long as top gear is usable most of the time. If the performance of the engine is such that it is necessary to keep changing down to a lower gear, then mpg is likely to go up, because of power losses inside the trans.
On the other hand if top gear is only used on the open highway and fifth is more useful at other times, then an OD would be the better choice, because fifth, on most Harley 6-speeds that are OD, is direct.
Hope that all makes sense!

All I can say is wow, wow, wow and grin from ear to ear. Festus your post is exactly correct. This transmission is simply awesome! Click click click into all gears and neutral is found so smoothly. Neutral was next to impossible to find with my old six speed. I also love the closer gear ratios. My bike feels like I just gained horsepower and torque. I also love the lower first gear. First gear is now like it should have came from the factory. I had a harley mechanic friend install the transmission as the special tools required were going to cost me over $600.00. We documented the install with pics which I will be posting in a few days. The install was pretty simple. Took longer to remove the exhaust, starter and primary stuff than it did to remove and install the transmission.
