I am going to buy a Warwick within the next month and I am having a difficult time trying to decide which one to get. I have narrowed it down to either a thumb or a streamer. I went to my local GC to play a few and they only had the thumb in stock. I tried asking about the real difference between the two (other then body shape) as far a sound and playablity but got no answers. Any of you warwick experts out there that could help influence my decision?! FYI - My favorite bassist is Dirk Lance and I know he plays a streamer but one of my other favorite bassists is the guy from Dave Matthews and he plays a thumb. I tend to play more of the funkish rock like incubus though.
