I agree with the use of highway pegs on the PA. From what I can see, the AeeDEA have the most range of adjustment. I think pegs are a great addition as I ride about exactly what the tires are rated for ( 60/40). Getting a chance to change up your foot position even for a bit can make all the difference on a long ride. On trips, we are right around the 600 miles per day mark.
I always offer the advice to anyone installing highway pegs to remember to note and adjust as necessary the following:
1. A stretched out "leg forward position changes the weight distribution on your pelvis. Generally, with forward stretched legs you sit more on your tail bone rather than the meat of your ass-cheeks. Take the time to try several different heights of the pegs before settling in for a 2500 mile trip.
2. The height of the seat and the type of seat also influence the position of said pegs. While you may think you found that "sweet spot" for those pegs, you may change seats down the road, and need to re-adjust. Taller seats may put additional pressure to your inner thigh, while shorter seats may cause a pull in your hamstring. Be aware of these factors and strive to find that sweet spot that makes YOU the most comfortable over the distance.
3. Having a friend shoot a picture from a tripod mounted camera gives you a chance to mess with several combinations and adjust as needed. Put the bike on the center stand and shoot a pic with you on it. Move the pegs, shoot another one, change the seat, bar clamps, etc. shoot a pic. Compare the pics side by side and note your spine angle. leg angle, and shoulders. After all, thanks to digital, you won't have to run over to the local Photomat and wait for the glossy 4x6's to get developed.
Hope this helps.
Keep er' movin.
