Wow, sintags allow me to format my views almost exactly like Ruby on Rails. I just want to make sure I'm using it properly.

How do I know when to use the {...} brackets, and when to use the Ruby style <%=...%> tags?

So far what I've been doing is using the brackets {} for operations such as looping, and using the ruby syntax for outputting and modifying via helper methods.

{loop products}

<div class="products">
<h2>{product.name}</h2>
<%= image_tag(product.image_url) %>
<%= h(product.description) %>
<span class="price"><%= number_to_currency(product.price) %></span>
</div>
{end}

Is this proper? Or can I implement sintags more effieciently?
