Don't listen to him, cutting the shaft down is no crime and if you can get a pair for a song and have them modified by a competent cobbler, it may make financial sense to do so. I've contemplated cutting my 8" SJs down to 6" countless times. May run you a bit, just be advised. I'd guess at least $150. Recommend contacting Kyle to get a true estimate from them what Baker's would charge for the service.
