Basically it depends on what you want to do with your fragment. If you just
analyze it on a gel and do a restrictition digest, Taq should be
sufficient. If you want to clone it, use a prrofreading pol, adjust
extension time to 1 min per kb and still sequence your clones before
proceeding any further.
