Anyone had a Brooks saddle upgraded by Selle Anatomica?

For the price of $49.95, they will cut a slot into your Brooks saddle and reinforce the saddle for the slot. It is just a guess on my part, but once I do this, I'm going to void my 6 month Wallingford no questions asked return option

After years of avoiding leather saddles, I finally came to the realization that to get a wide enough saddle that wasn't poofy required going with the B68. It is great as long as I'm sitting upgright or place an awkward bend in the back. But, a straight spine while in the drops and....ouch!

I tried excessive amounts of Proofide and trying to deform the leather to create a channel, but I fear it could be years before I succeed.

Brooks is testing out their 100 year old cutout, but if it succeeds, a B68 with a slot won't hit the market until December at the earliest (per their marketing person).

So, while perusing the Selle Anatomica site, I saw that they will retro fit your Brooks. Before voiding my Wallingford return and spending another $50 I was hoping someone here had some experience upgrading a Brooks.

Anyone?

Thanks
