upgrading to progressive suspension rear shocks

[frozenhawaiian]

hey guys, I'm in the process of doing a street tracker style rebuild on an 81 cx500 custom. both of the rear shocks were frozen when I got the bike so I'd like to replace them with some progressive rear shocks. I know both the 12 and 14 series dampers fit the cx series but they come in a number of lengths, which length would be proper? also which springs? I'm 210lbs would that be within spec for the standard springs or should I opt for the heavy duty springs? and between the 12 and 14 series, what would you guys recommend? the hydraulic 14 series or the gas charged 12 series? thanks guys.

from what ive read - heavy duty would be overkill unless your 2 up and loaded with gear- constantly
no idea about about comparison of 14 vs 12 series

thats what I figured about the heavy duty springs.
