First, getting your technique down will help a lot. That being said, better blades may help, but better is subjective. Tryablade.com has sample packs available. I'd stick with one blade type until you feel you have technique down, then try a new blade for several shaves with improved technique until you have narrowed it down to what works for you. As for closer, more pressure is NOT the answer. Improved angle and technique is.
