I think the 49 Niblick will fill that gap nicely for you. Also, you might find that you can use it off the fairway because I think way it plays feels between the 42 and the 56.
Will a 28* hybrid will usally play longer than a 28* 6i? A 32* hybrid might provide a better distance fit. I tried a used Ping G10 32* hybrid for a week once, and it was so much easier to hit than a 6i. Maybe I should have kept it, but that would have meant I'd also get need to get the 28* to fill the gap below it, and I was running out of money.
Thanks for the input, as for the hybrid, I like the Cleveland I have so I am just getting one club lower.
