I don't think setting the seat post at a comfortable height will be an issue for you.
I believe on the RW4 one could even be 7 feet tall and still get proper leg extension. I'm only six feet but I have a 34 inch inseam and I have the bottom sleeve set very shallow. With the standard seat post and the scale on the back of the post I had it set at about 6.5 whatever that is. None of the two telescoping devices were close to the minimum insertion depth.
FWIW I just installed a 27.2 Suntour suspension seat post on my RW4. I used a 30.8 sleeve (the bike shop didn't have a 30.9 sleeve) for the 27.2 seat post and it's working fine. I've put about 30 or 40 kms on it and it is holding position. I'm not sure why Rad's web site says the Suntour seat post isn't for the RW4 as they simply need to have a few sleeves in stock.
It works excellently. Very enjoyable riding now.
