88 Twin - Andrews 21 or 26?

Well, I am swapping cams here in my '06 FLHX and have most of the parts needed. I have purchased the SE Hydro Cam Tensioner Plate upgrade kit (which includes oil pump) and adj pushrods. Have all gaskets needed.

All I need is the actual cams to get this completed before the snow melts. Struggling between the Andrews 21 and 26 cams. This is a touring bike and my wife rides with me about 40% of the time so low end is crucial.

I am leaning towards the 21, but Andrews literation mention for 2-up go with the 26 - but also state its for 88-95 ci engines. I assume the 26 will not come to life w/o the 95 upgrade.

any thoughts/experience?

You really can't go wrong with either cam. If you don't see 4500rpms very often, the 21 is the right cam; particularly with two up riding. The 21 intake closes 5* earlier than the 21, shorter duration with about the same TDC lift. The earlier close means higher corrected compression and that equals torque. The earlier intake close and shorter duration move the curve to the left which is where you seem to want the power.
