Fairweather Tab Modulus Plates + Leather

What are the differences between the Fairweather tab 1.0 and the new Fairweather Modulus tab:

• The shape of the tab, the way it functions, fits together and works will not change. Current leathers and spacers will still fit. 
• material changed from Urethane plastic to high strength Acetal
• The surface finish is smoother
• comes with 3 plastic pieces, giving the archers the choice to shoot the tab either with a shelf, or without
• comes packaged in a case which can be used for travel/storage in your bow case
• The shelf plate will be made available in metal as a standalone upgrade item. The plate will fit with either the old tab or the new tab
• This product code is plate and facing material only. Finger spacer sold separately.
