Scotch 150 won't hurt anything, but it won't live up to the performance you'll get with something like Maxell UD 35-90, XLI 35-90 or Quantegy 407. For best performance I recommend using those. In fact I would choose Radioshack "Supertape" before I would go with the Scotch 150. The 1-mil Radioshack stuff is Ampex 642 in disguise, so it's good stuff. But recording is all about experimenting, so have at it!
