Tourstage X-Blade CBs

I thought that the TS-202s would have more offset for sure... but after looking at the Bridgestone Japan website (English Version), I'm just plain confused now. Here are the stats:

X-Blade CB with DG-S200

No. 3 4 5 6 7 8 9 PW

Loft 20 22.5 26 30 34 38 42 46

Lie 60 60.5 61 61.5 62 62.5 63 63.5

Face progression 3.25 3.25 3.75 3.75 3.75 3.75 4.25 4.25

Length 38.5 38 37.5 37 36.5 36 35.5 35

TS-202 with NS Pro 950 GH

No. 3 4 5 6 7 8 9 PW

Lie 61 61 61 61.5 62 62.5 63 63

Loft 20 23 26 29 32 36 40 45

Face progression 2.25 2.25 2.75 2.75 2.75 2.75 3.25 3.25

Length 38.75 38.25 37.75 37.25 36.75 36.25 35.75 35.25

Now, does a higher number mean more offset, or less? I tried getting more information on Japanese "standards", and came up with the following from the Precept website (Click HERE for the whole page in its entirety):

Face progression

Face progression is the distance (A) between the axis of the shaft (8) and the leading edge of the club head (10). When the leading edge extends out in front of the axis, face progression is expressed as a positive number (for irons generally, these values range from +6mm-0mm).

Goose (Off-set)

Goose is the distance between point (7), which denotes an imaginary line drawn from the hosel before it bends toward the face, and point (10), which signifies the leading edge of the club head. A club with a "straight neck" would have a goose of around 1mm, while a club with a "semi-goose neck" would have one of around 2mm, and a club with a "goose neck" one of over 4mm.

*Because calculations of goose are affected by differences in the thickness of the hosel or by differences in methods used to grind and polish forged clubs, face progression is primarily calculated today in relation to the axis of the shaft, which is not affected by such variations.

**"Goose" is sometimes referred to as "offset."

So, it seem to me that a higher "goose" = more offset. A higher "face progression" = less offset. I mean, the numbers make sense in this way, as shorter irons have less offset in general, right?

The higher number of face progression means that there is less offset. So the X-Blade Cb's have less offset then the 202's. hope that helps.

The J33 Combos are based on the X Blade CB's, at least for the longer and mid irons. Here are the offset figures.

When worked out converting the mm into inches, the 3 iron has only about 1/8" offset and the PW has only 1/16". That's pretty low offset for cavity backs, and is comparable to many sets of blades out there.

Phew! That's what I thought. So my comprehension of English isn't that bad after all... :cool:
