We all know it NEVER ends seriously, new first stages, new can light, hoses, stage kits, training etc ...why would I sell my BM stuff? Not hearing the benefits...
Why do you need new first stages?
Why do you need a new can light?
Why do you need new hoses? (you will need to add 2 shorty HP hoses and another SPG, so I guess you got me there)
Stage kits? Are you not already using stages in BM?
Training is strictly optional, if you have the time and location to work on the stuff yourself you can always just user a "mentor" friend.
It looks as if you really an NOT wanting to be convinced of anything nor is that necessary as sidemount is NOT for everyone or every situation. Sidemount is simply an option. My response was simply to show that "cost" is not as big of a factor that you make it out to be.
