i dont think the 32* was very rare. not much change on them either..basically just a stockish body that was a touch fancier with the milling. they are nice though and look amazing if you build it right.

check on impulse-owners they have a lot of the pls here and there for sale. if you want something much lighter you might look for a strange. i guess the weight difference isnt a big deal really. if you lug around an impulse no matter what its heavy by todays standards.
