I have a personal project at home of building a practice putting green, sand bunkers, pitching area etc and I was wondering what latest and greatest was in bent grass seed. I am familiar with PennEagle and PennCross but I must say the most impressive bent grass I've ever played was Crenshaw Bent. It was microfine and very true with lightening speed. I would appreciate any advice you can give. I witnessed a golf course being built and basically the greens were pure masonry sand. They drain fantastically but I would prefer a little soil with it. Anyhow, I will be doing some research and will start construction in March weather permitting. Thanks for any replies.
