Professional Schools

[tankmjg24]

I am currently debating on whether I should attend a professional umpire school this upcoming year. I will be starting my 10th year of officiating and have been told by some instructors (all amateur, none professional) that I should attend one as my skills are good and can become much better with the help of the clinic. I have the luxury of being able to have the time and money to attend a clinic if I do choose to. I am not necessarily looking to become a professional umpire, but to tone my skills. I have looked into Jim Evans 5 week school in addition to Wendelstedt's 2 week and 5 week school. What are everyone's thoughts on these schools in addition to attending one? Thanks in advance for any information given.
