I have sent Matt from H4L a PM and an e-mail regarding shaving me a new pod. Judging by the response on this forum, the H4L products look great! However, I am a custom bat virgin having gone with GM and Kookaburra throughout my career so far, I'm just hoping the product will deliver for the price premium. I could get a 909 Gunn and Moore for the same price and I know I would get a great product.
Can anyone convince me?
Whether or not it will convince you, consider the following.
Kook is a brand name that sub contracts it's batmaking out to big manufacturers in Asia. There is nothing to say that Kook bats are not good, indeed I have used them and been pleased. However if when you buy a Kook it is useful to know that regardless of model or grade, it will have been mass produced in a place where quantity overrides quality.
GM make most of their bats (down to 404 grade I believe) in the UK and their operation looks mighty impressive. I have no doubts that they care about the quality of their product, so yes, you can be assured you will get a good bat. However, using your example, a 909 model is only their third higest grade. For the same money you can get something from H4L or similar small maker that will be the best of the best.
From what you say you are quite picky about your bats, nothing wrong with that. Although if you decide on a Kook or GM you may have to wait a while to find one that ticks all your boxes. By getting one from H4L et al, you will be getting a bat made specifically for you to your specification. You can request weight, shape, handle shape, grains, heartwood, no heartwood. In fact you can specify just about anything you want, so you know you will be getting the bat of your dreams.
It is a popular misconception that just because a brand is small or not well known or relatively inexpensive that it is somehow inferior to the bigger brands. It simply isn't the case. Indeed more often than not the smaller brand will make a superior product.
One more thing to consider, when buying a GM, GN, Kook, Slaz, Adidas etc a large chunk of what it costs you will be paying for some pro to advertise the brand. With a smaller batmaker, this isn't the case, you are just paying for the craftsmanship.
Welcome to the forum, I hope that has helped.
