Derailleur Max Cog size

Hey,

I bought an old Shimano MT62 Deore derailleur for it's chain wrap capabilities and the idea that I'd be using a 32t cog on my bike. However, as I look at the cog break down, the HG50 13-34 is exactly what I'm looking for. 90% of the cassette is like what I have now, but it's got that last really low gear for bailing out.

So, the MT62 is rated for 32t max. Reading on here I see that most of the derailleur's out there are pretty conservative with their ratings. So I'm going to assume that this is the same case. Maybe a longer b screw will be needed?

My 1055 derailleur will clear the 28t cog it's rated for but I have the b screw maxed out which is why I'm asking.

Thanks!
