I'm looking to buy a longer travel FS 29er. I'm asking because there's a good sale on the 2018 RIP9 and wondering if there's much difference between the models to warrant paying premium prices for the 2019. On paper, head angle is 67 vs 66, travel 150 vs 140..... I'm not in a rush so I'm willing to wait for better prices on the 2019 RIP9 or other models including SB150, Ripmo, Rallon, Hightower LT. Thanks in advance for your input.
