I need to decide between a HS 81 T and an HS 81 R Stihl Hedge trimmer. The difference between the blades is R model blade designed for rejuvenation and heavy pruning. T model blade designed for trimming and sculpting. Which one would be the best to get. I can only afford one at the moment. Which would I likely use the most? Will the T model suffice with hand pruners for heavy pruning?
