I would highly recommend the Bitubo WMT's. You have arguably the nicest bike in production in modern times and the suspension on them in stock form is almost pathetic, especially in comparison to a nice suspension. The new shocks will do wonders for the bikes handling, scraping the floorboards and comfort for long days in the saddle. If you adjust the preload you can dial in the perfect height for you and then fine tune the riding characteristics with the compression and rebound adjustments. At your height, I would probably go with the 300mm Bitubo and never look back. Then you will realize how bad the stock suspension is and you'll be ready for a set of Traxxion Dynamics AK-20's. This combination will transform the bike and you will be much more comfortable and you'll experience much less scraping. My $0.02. If thats too much for your pocket book, take a look at the Bitubo WME's or perhaps the Progressive 940's mentioned earlier and a set of new front springs and a heavier fork oil or some monotubes. Sounds like you may ride pretty aggressive and the stock suspension is just too soft for you to to avoid the nose dive when you scrub off speed quickly by grabbing a handful of brake, you scrape when you put the 110" through its paces and you get a pucker factor going on when the bike responds lazy and bottoms out. Dont waste your time and money doing the lowering perch's IMO. Do it right the first try and enjoy your investment in the bike much more.
