If that 29% jump is in a range we seldom use, It shouldn't be a problem. If however it is in our cruising range it is a deal breaker. That range can probably be shifted some by using a different front and rear sprockets.

The Shimano MegaRange 7 speed cassette on my bike, And many other entry level bikes has a ridicules 41% jump to the next gear. 24 -34T. But with a triple chainring and the other 6 gears being properly spaced this drivetrain works very well. So it's not an issue. And for bikes with a single chainring, It might even be useful when climbing the big hill, Where a large change (25 - 30%) may actually be desirable.
