I basically go with products above 50 and avoid products with gravity >200. What you guys think is best to go for.
Some products with very high gravity quickly fizzle out while others with high gravity stay there. Ofcourse anything less than 50 is not recommendable. I usually try to see their trend over the last few months and see if they are able to maintain momentum. www.cbtrends.com www.nichejunky.com/ are useful tools.
