My 15 year old son has been using a 5 piece Tama Rockstar (larger shows), and a 4 piece Sonor Safari (smaller shows) very regularly for gigs. Lately he has been wanting to add a tom to the Sonor, and I have been hunting ebay for the appropriate hardware and a tom that is a reasonable match. However, a Sonor Force 2001 has become available locally and I was wondering if we should just sell the Tama and replace it with the Force 2001. That way, he can mix and match pieces from both sets to suit the gig, My question concerns the relative quality of the Tama Rockstar vs. the Sonor Force 2001(not familiar with this line)---are they both about the same quality? The Rockstar kit has served him well, and I don't want something that is lower quality.
